Abstract
The present invention is a negative electrode material for a non-aqueous electrolyte secondary battery, including negative electrode active material particles containing a silicon compound expressed by SiO, where 0.5≤x≤1.6, the silicon compound containing in its interior a lithium compound and one or more ions selected from Group 1 metal ions, Group 2 metal ions, and substitutable ammonium ions. This negative electrode material for a non-aqueous electrolyte secondary battery can increase the battery capacity and improve the cycle performance and the battery initial efficiency.
